Creamy Mushroom Gruyere Pasta Ingredients

• Heavy Cream – ½ cup (120 ml); gives the sauce its rich, velvety consistency.
• Unsalted Butter – 2 tablespoons; perfect for caramelizing the leeks without excess salt.
• Olive Oil – 2 tablespoons; helps prevent sticking during sautéing and adds flavor.

Step‑by‑Step Instructions for Creamy Mushroom Gruyere Pasta
Step 1: Cook the Pasta
Begin by bringing a large pot of salted water to a rolling boil. Add 12 oz of fettuccine or linguine to the boiling water and cook as per package instructions until al dente, typically about 8-10 minutes. Once cooked, reserve ½ cup of the starchy pasta water, then drain the rest and set the pasta aside, ensuring it stays warm.
Step 2: Caramelize the Leeks
In a large skillet, melt 2 tablespoons of unsalted butter with 2 tablespoons of olive oil over medium heat. Add the sliced leeks, stirring occasionally, and allow them to sauté gently for 12-15 minutes, until they become soft and golden brown. The sweet aroma will fill your kitchen, signaling that the leeks are perfectly caramelized and ready for the next step.
Step 3: Sauté the Mushrooms and Garlic
With the leeks caramelized, add 8 oz of sliced cremini or button mushrooms to the skillet. Cook the mushrooms for 6-8 minutes, stirring frequently until they are tender and start to release their juices. Add the minced garlic and sauté for an additional minute, allowing its fragrant notes to blend beautifully with the leeks and mushrooms.
Step 4: Create the Cheese Sauce
Reduce the heat to low and pour in ½ cup of heavy cream into the skillet. Gradually add ¾ cup of shredded Gruyere cheese, stirring continuously until the cheese melts completely, creating a creamy sauce that envelops the vegetables. Look for a smooth consistency, which will enhance the flavors of your creamy mushroom Gruyere pasta.
Step 5: Combine Pasta and Sauce
Gently fold the drained pasta into the sauce, ensuring each strand is well coated. If the sauce appears too thick, gradually add some reserved pasta water until you achieve the desired creaminess. Stir in the remaining Gruyere cheese and season generously with salt and freshly ground black pepper, tasting and adjusting as necessary to elevate the flavors of your dish.
Step 6: Serve and Garnish
Once everything is well combined and heated through, plate the creamy mushroom Gruyere pasta immediately. For a touch of freshness, sprinkle with chopped parsley, if desired. This comforting dish is best served hot, either on its own or accompanied by a simple side salad or a slice of garlic bread.

Make Ahead Options
These Creamy Mushroom Gruyere Pasta are ideal for busy cooks wanting to save time during the week! You can prepare the caramelized leeks and sautéed mushrooms up to 3 days in advance; simply store them in an airtight container in the refrigerator to maintain their delicious flavors. When you’re ready to serve, heat the leeks and mushrooms in a skillet, add the heavy cream and Gruyere cheese, then mix in the cooked pasta. If you prefer to prep everything, assemble the entire dish (except for the pasta) and refrigerate for up to 24 hours—just remember to add a splash of cream while reheating to preserve quality. Enjoy a delightful weeknight meal with minimal effort!
